KidZone Animal FactsGolden Carpenter Ants

Golden carpenter ants or Camponotus sericeiventris
are members of the Arthropod phylum, which is the scientific name for animals like insects, spiders and lobsters. They are also members of the
Formicidae family, which is the scientific name for ants.

Golden carpenter ants are 1/2 inch long ants that live in colonies in the tropical rainforests of Central and South America. Most ants dig "ant hill" colonies in the dirt but golden
carpenter ants dig their nests in the wood of dead trees or soft-wood living trees. They use their strong serrated mandibles (jaws) to burrow into the wood, building tunnels and rooms for
storing food and raising larva (their babies).

Golden carpenter ants also use these strong mandibles as weapons against their enemies. When threatened or when hunting, the ants bite their enemy with their mandibles to make a
wound. Then they move their abdomen over the wound to spray formic acid into it. This corrosive acid burns into the wound, causing extra pain and damage to the enemy.

Golden carpenter ants main method of defense is the fact that they work together. Their secondary defense is that they have quite a thick armor. Along with their allies (the
other ants in their colony), they are able to defend the nest, hunt and gather food cooperatively. Where one ant would barely be a minor pest to a large enemy, an entire group of the
ants can do enough damage to drive it away or even kill it. Despite their strong defenses, there are animals that eat golden carpenter ants - their main predators are birds and ant
eaters.

One of the most fascinating things about golden carpenter ants is that they are farmers! They look after "herds" of aphids -- not to eat them, but to eat the sweet excretions the
aphids leave behind when they eat leaves. Farming is a bit of a sideline for the ants -- their main food sources are collecting seeds, scavenging dead animals and hunting other insects.

Golden Carpenter Ant Summary:

Scientific name (genus and species): Camponotus sericeiventris

Phylum: Arthropod

Class: Insects

Size: 1/2 inch

Habitat: nest in living and dead trees in the tropical rainforests of Central and South America

Vocabulary Words:

Abdomen: The back end of the ant, it contains the ant's heart and stomach.

Antenna: An ant's two antennae are it's most important way of sensing the world around them -- they use them to tap things and to smell. The antenna stick out from the head and
the ant is able to move them around. The antenna have joints which allow the ants to bend them just like you would bend your finger using your finger joints.

Arthropod: Arthropods are an animal phylum that includes cold-blooded animals with segmented bodies, jointed legs and an exoskeleton. This class includes bugs like the ant and
larger animals like the crab. Learn more about arthropods.

Colony: A group of ants that live and work cooperatively together. A colony has at least one queen ant, but can have more. Think of it like an "ant city".

Exoskeleton: The hard outer shell of some animals, especially insects. Insects do not have bones inside of them, instead an ant has a hard shell that holds it together, helps it
move and acts like armor against predators.

Formic Acid: An acid produced in the bodies of ants. It smells a little like vinegar and will cause pain when it comes into contact with a wound. Ants use their formic
acid to defend themselves from predators and to help them when hunting prey. Formic acid is sprayed out of a specialized nozzle at the back end (abdomen) of ants.

Mandibles: Mandibles are the mouth parts of an ant, similar to jaws on people except that an ant's mandibles move horizontally (left to right) whereas people's jaws move up and
down. Mandibles are used to defend the ant but are also used to grab and tear apart prey.

Nest: An ant nest is usually dug underground with a small mound of soil piled up around it -- also known as an ant hill. However in the case of carpenter ants, nests are built
in living or dead wood. An ant colony can be made up of many ant nests -- just like a human city can have many apartment buildings.

Predators: Animals that are trying to kill and eat the ant. A carpenter ant's main predators are birds and ant eaters.

Prey: Animals that the ant is trying to kill and eat.

Thorax: The middle part of the ant's body. This is where the six legs of an ant are connected to the body.
